Abstract :
This paper investigates the common mode voltage in multilevel DTC drives and proposes a new algorithm for multilevel flying capacitor drives to reduce its common mode voltage. The new algorithm uses only those voltage space vectors which lead to lower common mode voltage. The simulation results in MATLAB/SIMULINK verify the capability of the algorithm in reducing the common mode voltage without degrading the electromagnetic torque and speed response.
